A few of us here at BGR can make just as nice a weld with a mig as they can with a tig.It's just a little bigger weld.MS cages are usually .135 thick so when you weld two pieces of .135 material you want at least .270+- of weld width and at least the same weld thickness of the the material .135+- at the crown.These specs are from the Steamfitters weld testing for power plants and pressure vessels. But then what in hell do I know,I was only certified in only 5 states for bridge and structural and heavy equipment modification and repair.I was a student of the late Art Livinston one of the best in the business.I didn't take the test for nucular power plants.

You never win on Mopars using facts and logic - you should know better!!! As we know, any weld quality, both appearance and integrity, is dependant on materials used, surface fit/prep, and welder skills. As I said, I am trying to get an answer without trying to insult anybody.
